摘　　要：目的探讨三维(three dimensional,3D)缩流颈面积(vena contracta area,VCA)在不同病因下三尖瓣反流(tricuspid regurgitation,TR)诊断的准确性和实用性。方法2019年3月至2021年5月,92例确诊为TR的患者接受了二维(two dimensional,2D)和3D经胸超声心动图检查,测量其3D VCA和依据近端等速表面积(proximal isokinetic surface area,PISA)计算的3D有效瓣口反流面积(effective regurgitant orifice area,EROA)的相关性和一致性,并以综合2D多参数方法作为参比方法计算其诊断重度TR的界值。结果最终纳入85例患者。3D VCA与3D PISA EROA在原发性TR和继发性TR中作用相似,且有一定的相关性(原发性TR:r=0.831,P<0.01;继发性TR:r=0.806,P<0.01)。Bland-Altman分析显示3D VCA和3D PISA EROA相比会高估TR(总患者人群中高估62%,原发性TR中高估51%,继发性TR中高估74%)。在继发性TR中,3D VCA诊断重度TR的界值为0.45 cm^(2)(敏感性89%,特异性82%);结合临床症状、阳性2D PISA EROA结果和对重度TR分级的3D VCA,其χ^(2)值高于仅考虑临床症状或合并临床症状和阳性2D PISA EROA的χ^(2)值(42.168 vs.26.059,16.759,P<0.01)。结论3D VCA会高估TR,在继发性TR中对诊断重度TR具有较高且增量的诊断效力。Objective To explore the cut-off value of three dimensional(3D)vena contracta area(VCA)in diagnosing severe tricuspid regrugitation(TR)under different etiologies and its accuracy and practicality in clinical application.Methods From Mar 2019 to May 2021,ninety-two patients with confirmed TR underwent two dimensional(2D)and 3D transthoracic echocardiography.The correlation and consistency between 3D VCA 3D calculated based on the proximal isokinetic surface area(PISA)effective regurgitant orifice area(EROA)was calculated.Comprehensive 2D multi-parameter method was used as a reference method to calculate the cut-off value of the diagnosis of severe TR.Results A total of 85 patients were ultimately included.3D VCA and 3D PISA EROA had similar and acceptable correlations in both primary TR and secondary TR(primary TR:r=0.831,P<0.01;secondary TR:r=0.806,P<0.01).Bland-Altman analysis showed that 3D VCA overestimated TR compared with 3D PISA EROA(62%overestimated in the total patient population,51%overestimated in primary TR,and 74%overestimated in secondary TR).In secondary TR,the cut-off value of 3D VCA for diagnosing severe TR was 0.45 cm^(2)(sensitivity 89%,specificity 82%);combining clinical symptoms,positive 2D PISA EROA results and 3D VCA results for severe TR,the chi-square value was higher than those only included clinical symptoms or incorporated clinical symptoms and positive 2D PISA EROA results(42.168 vs.26.059 and 16.759,P<0.01).Conclusion 3D VCA would overestimate TR,and had high and incremental diagnostic value for evaluating severe TR in secondary TR.
